Question about Toshiba 50H72 50" Rear Projection Television
TV orginally had the bowed effect. I replaced both the STK392-110 IC's. I also checked the resistors and they checked out fine. However after replacing the IC's the power LED will come on solid red but there is no picture and I can't even get a picture when trying to bring up the menu. Any thoughts.
When I originally removed the board with the convergence IC's I labeled all of the wiring harneses with number tape as I keep a multi number roll on hand as I am a radio broadcast engineer. However there was one set at the very back of the board behind a large heat sink I didn't label because that location was the only place they would fit. When replacing the board after replacing the IC's I missed that particular wiring harness as it didn't have numbers and I didn't see the harness laying among the other wiring. After removing the board to check my soldering work that's when I discovered the harness. I plugged that set in along with the rest, replaced the board, and after cleaning the CRTS's and the mirror the set worked good as new and a much sharper, cleaner picture. Thanks for the information on your forum as it always feels to repair something yourself and save a few hundred bucks to boot.
